The objectives of this study were to (1) determine if results from a previous study of a mesquite woodland utilizing groundwater in the Californian Sonoran desert were generizable to mesquite systems in other deserts where root depth varied with ecosystem type and (2) examine possible relationships of soil properties and host-plant phenology to rhizobial concentrations. Soil forming and hydrologic processes that impart morphological features, however, extend considerably below these horizons. Precise adherence to Soil Taxonomy places an arbitrary constraint on field observations at 2 m. Soil scientists routinely observe C and R horizons and deeper underlying substrata in gravel pits, road cuts, barrow pits.
There also is a Keys to Soil Taxonomy document providing the taxonomic keys necessary for the classification of soils in a form that can be used easily in the field. It also acquaints users of soil taxonomy with recent changes in the classification system, incorporating all changes approved since e Electrical conductivity of saturation extract Soil Science in Philadelphia, USA (book: IUSS Working Group WRB, ; 2 World reference base for soil resources The field tours associated with the meetings of the IUSS Commission on Soil Classification in Chile () and the United States (Nebraska and Iowa, ) were.

of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field.
It is important that soil description be done thoroughly; it serves as the basis for soil classification and site evaluation as well as interpretations on the genesis and environmental functions of the soil. deal with the inherently complex nature of soil data.
You should understand that soil mapping units are inherently complex; the mapping unit polygons rarely consist of a single type of soil. Commonly mapping units are complexes or associations of multiple soil types. A given unit might have 55% one soil, 40% of another and 5% of other soils.
Soil classification is a dynamic subject, from the structure of the system itself, to the definitions of classes, and finally in the application in the field. Soil classification can be approached from the perspective of soil as a material and soil as a resource.

Seasonal high saturation is always within 15 cm of the soil surface; on certain landforms, there may be inundation above the surface.

Soil Taxonomy classifies soils within a hierarchy of six categories. Only the highest-level category, order, is discussed here. Soil orders are named by adding the suffix -sol to a root word, as shown in the table of the U.S. Soil.Soil Survey Staff.
